Calculation false with datediff

Hello,

I have a google sheet in which I have a table like this

Keycreated DateRésolution DatePriority
118/12/2023 02:34:2404/09/2024 07:31:00Nice to have
229/03/2024 08:06:4610/04/2024 07:16:00Current
320/03/2024 05:59:1210/04/2024 07:16:00Current

On Looker Studio, I would hive the average time to resolution by priority : 

(resolutiondate - created date) / Number of Key 

I use datediff

but the result is false : 

aurelie_pilette_0-1728315636233.png

For Nice to have, the result must be 260 and not 275

For current, the result must be 16 and not 62

So, i don't undertand the difference and maybe my configuration is false.

Who can help me please ?

Bonjour @aurelie_pilette 

Could you share the formula of "Temps de ..." and confirme that created Date and Résolution Date are date time fields please?
